Gridfinity Fish Tank (10-ish L)

We've all been there. You've just printed the perfect Gridfinity system. But as you close the door to your workshop you wonder to yourself. "Do my tools ever get lonely without me?"

Well I have the solution! This 3D printable gridfinity fish will allow you to keep like, idk, a goldfish or something. Give your tools the shiney new pet they deserve!

(Full disclosure I don't have a printer so can't print and try this but if anyone does please let me know how it goes.)
